Spare hose kit which is OEM with the Bravo 101 pump
Very popular as an upgrade to many pumps like Bravo 100, as this hose has the Screw fitting a the Pump end and the 20mm Mother Bayonet fitting at the output end, as well as the selection of fittings supplied with the Bravo 101 pump.
May fit other brands of pumps, but care should be taken as so many different sizes and pitches of threads are appearing now with the less mainstream products.
